To all whom it may concern:

Be it known that I, MINA L. M. Puck, a citizen of the United States, residing at Hamilton, in the county of Madison and State of New York, have invented certain new and useful Improvements in Cork-Pullers, of which the following is a specification, reference being had to the accompanying drawings.

This invention is an improved automatic cork screw for extracting the corks from bottles, jugs and other like vessels, the object of the invention being to provide a cheap, simple, strong, durable and eHective device of this kind, which may be operated automatically for extracting the cork, the invention consisting in the construction, combination and arrangement of devices, hereinafter described and claimed.

ln the accompanying drawings-Figure 1 is a vertical central sectional View of an automatic cork screw constructed in accordance with my invention. Figs. 2 and 3 are detail transverse sectional views of the same on the planes indicated by the lines a-ca and -b respectively.

In accordance with my invention I provide a barrel 1 which is open at one end as at 2, and is closed at the opposite end as at 3, and is of such size and shape as to enable its open, lower end to be slipped over thel neck of a bottle. A handle et is at the upper closed end of the barrel and is secured thereto by a stem 5, the lower end of which is secured to the upper end of the barrel at the center of the same, the upper end of the said stem being shown as provided with an eye or ring 6, through which the handle extends.

n the under side of the cover 3 of the barrel, at the center of the same, is a socket 7 which is the lower terminal of the stem 5 and is here shown as formed by a series of segmental arms or claws 6 arranged in substantially spherical form.

Tn the center of the barrel 1, and parallel therewith is a shaft 9 which is provided with a worm groove 10, which extends from end to end thereof. The upper end of the said worm shaft is provided with an annular head 11 which has ratchet teeth 12. A screw stein 13 is secured centrally in the upper end of the worm shaft and is provided at its upper end with a spherical head 14, which is revoluble in the socket 7 and is held therein by the claws or arms 8 which form the wall of the said socket, and hence the upper end of the worm shaft is swivelly connected to the closed upper end of the barrel. A pawl 15 is pivoted at 16 to an arm or lug 17 which extends from the lower side of thecover 3 of the barrel, and the said pawl is normally engaged with the ratchet head 11 of the worm shaft by means of a spring 18. The said pawl has an arm 19 which extends up through and is free to move in a slot 20, in the cover 3 of the barrel and enables the pawl to be released from the ratchet head of the worm shaft at will. A cork screw 21 is secured to the lower end of the said worm shaft.

A disk or plunger 22 operates in the lower portion of the barrel 1 and is movable lengthwise of the said barrel. The said disk is provided at opposite sides with external ears 23 which operate in vertical slots 24 in opposite sides of the barrel. Hence while the said disk is free to move lengthwise in the barrel, it is prevented from turning in the barrel by the ears 23 and slots 24. The said disk has a central opening 25 through which the cork screw may extend when the disk is moved up in the barrel, and the disk is also provided with downturned points 26a to engage in the upper end of the cork and prevent the cork from slipping. The disk is provided at suitable points with a suitable number of upwardly extending arms 26 each of which is here shownl as provided on its inner side, where it is opposed to the worm shaft, with a socket 27 in which is mounted a ball 2S, the said balls forming anti frictional ball bearing extensions of the said arms, and which engage the spiral or worm grooves of the worm shaft.

A strong spiral spring 29 is disposed in the barrel. The upper end of the said spring engages the closed, upper end of the barrel, and the lower end of the said spring bears on the upper side of the disk 22, and the said spring serves to normally move the said disk downwardly and keep the same ordinarily disposed at the open, lower end of the barrel.

The operation of my improved automatic cork screw is as follows: To extract a cork from a bottle or the like, the lower open end of the barrel is placed around the neck of the bottle, and the disk 25 is thus disposed on the upper end of the cork, and its points 26a engage the cork and keep the of the worm shaft in such direction. Havin the reverse direction, and hence when the upper end of the cork. To release the cork spring 29 forces the disk outwardly in the ing thus firmly engaged the cork screw in the cork, the operator then pulls upwardly or outwardly on the handle 4, and thereby extracts the cork. It will be understood that the coacting ratchet head of the worm shaft and pawl, while permitting the worm shaft to turn in the required direction to embed the cork screw in the cork, serves to preventcasual rotation of the worm shaft cork has been thus eXtracted,`the spring 29 is under tension and the disk 22 is up in the barrel at some distance from the lower open end thereof, and is in engagement with the from the cork screw,the operator with one finger by means of the arm 19, disengages the pawl from the ratchet head of the worm shaft, and thereupon the tension of the barrel, the balls 28 ofthe disk arms 26 coact with the worm grooves of the worm shaft to rotate the worm shaft and cork screw in the required direction to withdraw the cork screw from the cork.

I claim l. The herein described automatic cork screw comprising a barrel closed at one end, i and open at the opposite end, a disk mov- Copies of this patent may be obtained for five cents Washington, D. C. i

ceases Vable longitudinally in the barrel, said disk grooves, the said disk being provided with tappet elements engaging said worm grooves, the said shaft being swivelly connected to the closed end of the barrel, and provided with a ratchet head, a pawl carried by the barrel to engage the said ratchet head and prevent rotation of the barrel in one direction, an operating handle attached to the barrel, a cork screw secured to the worm shaft, and a spring to move the disk outwardly in the barrel.

2. In a device of the class described, thc combination of a barrel having a closed end and an open end, a central axial shaft in the barrel and swivelly connected to the closed end thereof, said worm shaft having a ratchet head, a spring-pressed pawl pivotn ally connected to the closed end of the barrel and normally engaged with said ratchet head, a cork screw attached to the outer end of the worm shaft, a handle connected to the closed end of the barrel, a disk movablc longitudinally in the barrel and having a central opening to clear the cork screw, said disk and saidbarrel having coacting devices to prevent the disk from turning, and said disk being further provided on its outer side with points to engage a cork, and a spring in the barrel and bearing against the inner side of said disk to move the same outwardly for the purpose set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
